Diagnostic Fault Information

Circuit/System Description

When the heated seat function is active, the rear heated seat module (RHSM) supplies battery voltage through the element supply voltage circuit to

the seat heater elements. The RHSM controls the seat temperature by providing a pulse width modulated (PWM) ground through the heated seat

element control circuit to the seat heater elements. The RHSM then monitors the current flow through the heating element and the temperature

sensor rate of change to verify correct operation.

Conditions for Running the DTC

The RHSM must be powered and the heated seat must be enabled.

Conditions for Setting the DTC

B2425 04 or B2430 04

The RHSM does not detect a temperature change within 210 seconds.

B2425 0A or B2430 0A

The RHSM detects that the set point temperature has not been reached within 8.5 minutes.

B2425 0B, B2425 0E, B2430 0B, or B2430 0E
